When can you ride a motorcycle in a Bus lane in NSW ?

Illegal use of a bus lane incurs a fine with loss of points.

If you’re confused, frustrated and tempted with bus lanes, you are not alone. Simply put, there are two types of bus lanes: Bus lane (or B Lane) and ‘BUS ONLY’.

Bus lane or B Lane can be used by public buses. Bicycles, taxis, hire cars (with HC plates), and motorcycles are also permitted to ride in these lanes.

General traffic are also allowed in bus lanes for up to 100m in order to:

Turn left or right into or out of a street.
Enter or leave a property adjacent to the bus lane.
Pass another vehicle that has stopped to turn right or to avoid an obstruction.

’BUS ONLY’ lanes are for the exclusive use of buses, and no private vehicle is ever allowed to drive in them. They will be clearly marked and often also have special traffic lights that allow buses priority when moving off at intersections.
